ENVELOP.

To all whom it may concern "Be it known that I, RAYMOND A. MERRILL,

acitizen of the United States, and a resident of New York city, county and [State of New York, have invented certain new and useful novel construction, which can be readily opened by tearing ofi a doubled rim portion along a line of reduced resistance, while means are provided for ascertaining whether theletter inclosed by the. envelop, pro ects be 0nd said line into said rim port1on. the way the letter may be pushed back into the main body. of the envelop, prior to the tearing operation, so that it will not become mutilated by the opening process.

In the accompanying drawin Figure 1 is a front view of an envelo em odying my invention; Fig. 2 a plan 0 the blank; Fig. 3 an enlarged cross section on line 3-3 Fig.

1 and Fig. 4 an enlarged cross section on line 4-4 Fig. 1. I 26 Along one of the transverse edges 1, of an envelop there extends a weakened line 2,

. which ispreferably formed by means of a row of minute apertures punched through the main section 3 as well as through one of the side flaps 4, and part of the end flaps 5.

In this way the envelop is'divided into a main bodyor pocket adapted to house a letter or other insert, and into a doubled narrow tearing strip 6, flanking said pocket.

In order to ascertain vghether the letter, between the foldsof tearing strip projects furnished with a sight hole '6, the latter is l or window 7, which should extend close up to the tearing line 2. Before opening the envelop, a glance through the sight hole will sufiice to ascertain whether or not strip 6 is clear of the letter, so that the latter may, if

necessary, be pushed out of harms way into the main body of the envelop. This can be I readily accomplished, by slightly tapping the envelop or in other simple manner.

When the sight hole discloses the fact that the letter nolonger projects beyond-line 2,

-for'ate sectlon 8 will remain ateach'en I strip 6 may be torn off so that the letter may be removed without being injured.

In constructing the envelop, a sight holes is formed in the tearing strip portion of the main section 3 of the blank, as well as in the tearing strip portion of the side flap 4', so that when the blank is folded and the strip is thus doubled, the two holes will become alined, and form conjointly a window pass- Patented June 8, 1915.

ing clear through both moities of the strip. Thus there will be a clear line of vision'- through the envelop when the strip is empty,

and anobstructed line of vision, when the strip is occupied.

I prefer to so construct the envelop that the weakenedline 2 does not extend along the entire width of the envelop, but stops short some distance from both of its longitudinal edges, so that in-this way an ini eri o the line. This imperforate section constitutes a reinforcement which protects. the envelop from a starting tear at the ends of the weakened line through r'ough handling in the mail. In order to obtain this desirable result, the tearing line stops short some distance from'the longitudinal edges 9 of the envelo on the main section 3vas well as on the si e flap 4 and end flaps 5, so'that when the blank is folded the imperforate portions of the various sections will become juxtaposed.

As shown in the drawing the opening 7 is arranged in close proximity to weakened line 2, and merges 1nto the same. In this way there is formed by the opening and in the weakened line, a clearance or section of operation tobe here read1l started by using the opening as a finger ho e. The construction s particularly desirable with envelops having the reinforced sections 8, inasmuch as it dispenses with the necessity of so care- I fully gaging the starting tear, as to cause it to run out into. the weakened line. I claim 1. An envelop provided with a weakened line, to form. a tearing strip, and with an opening .forined in said strip and nierging .into the weakened line. 2. 'An envelopprovided with a weakened 5 pair oflalinedsight openings ormed in the olds of said strip and merging into. the weakened line.

3. An envelop provided with a weakened line extending along one of the transverse edges of the envelop to form ate'a strip 10 j said weakened lineterminatin line, to form a doubled tearin strip, and "a stancefrom hoth longitudinal edges 0 the envelop, and-with an opening in said tearing strip that merges into the weakened line.
